“…There has been research on the efficiency of lithium extraction, both ancient and novel. For example, fluorinated β-diketones have been investigated to separate lithium from sodium, potassium, rubidium, and caesium, due to their poor selectivity for lithium [46]. More recently, N-butyl pyridinium bis[(trifluoromethyl)sulfonyl]imide solution was found to have a high efficiency for lithium extraction from brines [47].…”

This literature review gives an overview of the lithium industry, including the lithium market, global resources, and processes of lithium compounds production. It focuses on the production of lithium compounds from spodumene minerals. Spodumene is one of the most critical minerals nowadays, due to its high lithium content and high rate of extraction. Lithium is one of the most sought-after metals, due to the ever-growing demand for lithium-ion batteries (LiBs). The data on lithium extraction from minerals is scattered through years of patents, journal articles, and proceedings; hence, requiring an in-depth review, including the comprehension of the spodumene phase system, the phase conversion processes, and the lithium extraction processes.

“…Lithium was selectively extracted from near‐neutral aqueous solutions of alkali metal salts. The selectivity of the fluorinated β‐diketones for lithium over the alkaline earth was found to be poor . For better extraction TOPO was used along with fluorinated β‐diketone and high separation factors were obtained from sodium, potassium, rubidium, and cesium.…”

“…For better extraction TOPO was used along with fluorinated β‐diketone and high separation factors were obtained from sodium, potassium, rubidium, and cesium. The mechanism by which this was achieved involves formation of the trioctylphosphine oxide adduct of a lithium chelate of a fluorinated β‐diketone, which is then readily extractable into an organic diluent . Kunugita et al studied the extraction of lithium and its separation from sodium in a sulfate system using LIX 51 (α‐ perflouroalkanoyl‐m‐dodecylacetophenone) and LIX 54 (α‐acetyl‐m‐ dodecylacetophenone) .…”

Separation and purification of lithium by solvent extraction and supported liquid membrane using various commercial and non-commercial extraction has been reviewed. In solvent extraction, extraction by chelating extractants, acidic extractants, solvation extractants and mechanism involved in the extraction has been discussed. Solvent extraction of lithium by solvation extractants like; TOPO, DBM, TBP, and LIX and synergism of diketone with various solvation extractant combinations have been reviewed. Finally, lithium extraction by supported liquid membrane using various extractants has been reviewed. The reported processes mainly lacking in analysis of chemical mechanism involved in the lithium extraction using all these extractants are analyzed and discussed.

Lithium recovery from an aqueous resource was accelerated by electrochemically driving the transformation of MnIV/MnIII with a spinel λ‐MnO2 film electrode. A λ‐MnO2 electrode without binders or conductive additives is preferred for achieving a large capacity at high current density and long‐term cycling capability. In this study, a film of Mn(OH)2 was first deposited on the surface of Pt or graphite substrates owing to alkalization near the cathode, then it was oxidized to a Mn3O4 film by air, followed by being hydrothermally lithiated to LiMn2O4 spinel and, finally, it was turned into the λ‐MnO2 film electrode through potentiostatic delithiation. The results show that the charging/discharging electric capacity of the fabricated λ‐MnO2 film electrode was up to ≈100 mAh g−1 at a current density of 50 mA g−1 in 30 mm Li+ aqueous solution, twice that of the λ‐MnO2 powder electrode. Also, 82.3 % lithium capacity remained after 100 cycles of an electrochemically assisted lithium recovery process, indicating high availability and good stability of the λ‐MnO2 spinel on the electrode. The energy consumption for each cycle is estimated to be approximately 1.55±0.09 J, implying that only 4.14 Wh is required for recovery of one mole of lithium ions by this method.
